pmdomain: imx: gpcv2: Adjust delay after power up handshake

In the Linux kernel, the following vulnerability has been resolved:

pmdomain: imx: gpcv2: Adjust delay after power up handshake

The udelay(5) is not enough, sometimes below kernel panic
still be triggered:

The correct way is to wait handshake, but it needs BUS clock of
BLK-CTL be enabled, which is in separate driver. So delay is the
only option here. The udelay(10) is a data got by experiment.
